HP Monitor L1710 -- power light flashes green when I turn on PC, screen flickers black w/ no image

[tom_degennaro]

Hello,

Last night I turned off my PC w/ a HP Monitor L1710, which I did not turn off. When I turned on my PC this morning the screen does not "turn on" -- the green light next to the power button flashes on and off, and the screen flickers between shades of black, like it's trying to turn of. This PC usually is not turned off at night (this is a work PC, and I just started to working at this desk (almost) never turned the PC off at night, so I wonder if it has something to do with that. I've turned the PC on and off multiple times, unplugged the power cable (for the monitor) and cable that runs from the monitor to the PC. I believe the PC is on (cd drive opens and closes, recognizes my phone when I plug it in to charge), so I don't think that is the problem. 

I see a lot online that it may be stuck in power saving mode. 

Any thoughts? Any help or ideas would be greatly appreciated

Tom D.

Hello @tom_degennaro,

Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.

I understand that your monitor is not coming on when you turn on your PC. I am setting out some steps for you to try for you to try below:

Step 1. Unplug the power cord from the monitor and the wall outlet

Step 2. Hold the power button down for one minute

Step 3. Plug the power cord back into the monitor and then the wall outlet (not a powerbar or surge protector)

Step 4. Press the Menu button on the front of the monitor

Step 5. Navigate to the Factory Reset option and select it.

If the issue still persists after the above steps try the monitor on another computer. If the monitor still does not work at that point then, it appears to be a physical issue and I think it would be best if you contact HP Technical Support for repair options.

If however the monitor works on another computer you have an issue with the computer it was originally on. If the computer is an HP computer I would be happy to assist you with, but first I would encourage you to post your product number for the computer. I am linking an HP Support document below that will show you how to find your product number. As well, if you could indicate which operating system you are using. And whether your operating system is 32-bit or 64-bit as with this and the product number I can provide you with accurate information.

How Do I Find My Model Number or Product Number?
Which Windows operating system am I running?
Is the Windows Version on My Computer 32-bit or 64-bit?

Please re-post with the requested information and I would be happy to provide you with assistance. Thank you for posting on the HP Forums. Have a great day!
